Intimacy

I find it difficult to form bonding with people. Especially, with my fiancee, even though we share a lot of things, i find it hard to trust her completely and avoid getting emotionally close to her. This happens also when i become successful in job / career. I find people to be some kind of threat to my success and future, so try to get emotionally absent for them. Please advice as this is really affecting my life and social being.

In a way you are right. If you are successful, people tend to envy you and they might be a threat to your success. Try to find out what your fiancée needs from you. If you are sensitive to her wishes, you increase the chances that she will stay and make you happy.
